1. A method of operating a fuel cell stack comprising fuel cells separated by interconnects, the method comprising:
flowing a fuel from a fuel inlet opening in the interconnects to a fuel outlet opening in the interconnects through fuel channels located between fuel ribs in a primary flow field on a first side of the interconnects, wherein a larger fuel mass flow is directed through the fuel channels extending along a periphery of the primary flow field than through fuel channels extending through a middle of the primary flow field; and
flowing air on a second side of the interconnects.
